Re: INCOMPATIBLE_LICENSE - how to use it properly?

John Ernberg

Hi Alex,

I will give this a try on master.

One question though, will this still catch build-only libraries? (i.e. a
library that consists only of headers). I don't think we have such
recipes right now, it's more to understand how this feature works.

Thank you.

Best regards // John Ernberg

On master, you can set INCOMPATIBLE_LICENSE in the image recipe, rather
than globally, then the check would only be performed on items that
actually go into that image.

Warrior does not have that feature yet, I think, so your only option
there is meta-gpl2.

I have been trying to use INCOMPATIBLE_LICENSE to filter out
licenses for us from our images. I started simple and picked the
examples from the manual (AGPL-3.0, GPL-3.0 and LGPL-3.0).

Currently we're based on Warrior, but I also did a short test on master
(results later in the message)

Our images use systemd as init system. We use busybox ash as shell on
these images for now.

When setting the INCOMPATIBLE_LICENSE according to the manual example,
systemd cannot be built anymore because bash is being skipped due to

Turns out that because systemd-bash-completion and
systemd-kernel-install both rdepend on bash, we can't build systemd at
all, because bash is not buildable. Even if we're not installing those
features of systemd.

A dive into TaskData suggests that all the rdepends of all packages
provided by a recipe are flattened into depends of the recipe when
testing buildability.

A quick test on master from about 2 weeks ago show the same behavior.

For the test on master all I did was change the DISTRO_FEATURES of
core-image-minimal to include systemd.

Am I using ICOMPATIBLE_LICENSE properly so far?
If so, is being unable to fulfill an rdepend for an unused package
to fail the whole build, and how can I avoid it short of including
meta-gplv2 or writing lots of .bbappends to remove the dependencies?
Otherwise, where did I go wrong, and what should I be trying instead?

Thank you.
